Can you imagine doing just that?
While traversing a rock formation by yourself, you discover a ledge. It’s past sunset, so you start making your bed. You hunker down to work, attaching all the necessary ropes, pulleys and anchors, and secure one to your harness. You test the net. “This should do - I think.”
You swing yourself into the hammock. “I can’t believe I’m about to sleep 10,000 feet above ground. Oh yeahhhh!”
5 minutes later: “I’m not getting any sleep tonight”. -.-
